Operator’sManual
Introduction
Description of the 3M™ BairHugger™ Temperature
ManagementSystem
The BairHugger temperature management system consists of a
Model 775warming unit (with optional rolling stand, and other
accessories) along with a 3Mwarming blanket, BairHugger warming
gown, or the 3M™ Ranger™ 241blood/fluid warmingset.
The BairHugger warming unit is attached to the warming blanket or
warming gown by means of a flexible hose. Warm air is generated
in the warming unit and flows through the warming unit hose and
into the blanket or gown. Depending on the model, the 3Mblanket
or gown is placed either around, over, or underneath the patient.
Small perforations on the blanket or gown allow the warm air to be
dispersed over the patient. For blood/fluid warming applications, the
Model 241blood/fluid warming set is inserted in the warming unit
hose. When the warming unit is turned ON and a temperature setting
is selected, warm air flows over the Model 241tubing and warmed
blood/fluid exits from the distal end of the tubing. For additional
information on 3Mblankets, gowns, the 241warming set, or other
accessories visit us online atbairhugger.com.
This manual includes operating instructions and warming unit
specifications for the Model 775warming unit. You can use the
Model 775warming unit in all clinical settings where the patient may
feel too warm or too cold; including the operating room to provide
patient temperature management. For information about using
3Mblankets, gowns or the 241blood/fluid warming set with the
Model 775warming unit, refer to the respective Instructions forUse.
Indications
The BairHugger temperature management system is intended
to prevent and treat hypothermia. In addition, the temperature
management system can be used to provide patient thermal comfort
when conditions exist that may cause patients to feel too warm or too
cold. The temperature management system can be used with adult
and pediatricpatients.

What to Do If a Fault Conditionoccurs
The Model 775warming unit software recognizes several
non-hazardous conditions and reports those conditions as faults.
When a system fault occurs, the software stores the fault code
in memory, the amber Fault indicator light flashes, and an alarm
sounds. The warming unit automatically turns the heater, blower,
and operating mode indicator lights OFF. The control panel will not
respond tocommands.
Note: Pressing any button will silence thealarm.
IF A FAULT CONDITIONOCCURS:
1. Unplug the warming unit and wait for 30-60seconds.
2. Reconnect the warming unit to a grounded power source. The
warming unit will perform the normal power-on-reset sequence
and then enter the Standbymode.
3. Reselect the temperaturesetting.

FAQ / 0-8811-8718-34
Frequently Asked Questions (FAQ) on Filtration
What filter is used in the 3M™ Bair Hugger™ Model 775 warming unit?
The Model 775 uses the same lter media as has for many years been used with prior Bair Hugger -700series models. That lter media is
classied on an industry-standard scale as MERV 14 at 48 CFM (cubic feet per minute) under ASHRAE Standard 2012-52.2: Method of
Testing General Air Ventilation Air-Cleaning Devices for Removal Eciency by Particle Size.1,2
What is a MERV rating?
The Minimum Eciency Reporting Value, or MERV, is a measurement scale to rate the eciency of an air lter as a
function of particle size based on the ASHRAE Standard 2012.1,2.1,2-52.2
What is the MERV rating recommended for operating rooms?
ASHRAE Standard 2013-170, Ventilation of Health Care Facilities, provides standards and guidance on the design
requirements for ventilation systems utilized in health care facilities.3 The standard recommends that operating rooms
utilize a lter that is equivalent to MERV 14.3 This MERV rating is specic to the ventilation system in the hospital’s
operating room.
What is the MERV rating recommended for patient warming devices in the operating room?
There is no ltration standard for patient warming devices utilized within the operating room. The ASHRAE Standard is a
standard used to assess lter eciency in health care ventilation systems.
Is a HEPA filter necessary?
No. We are not aware of any evidence or claim demonstrating that a HEPA lter improves patient safety.
What is the ASHRAE 52.2-2012 standard?
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is a global organization
focused on research, education and standards for heating, ventilation, air conditioning and refrigeration. The ASHRAE
standard 20121,2-52.2 provides test methods for air intake lters to ensure standardization in classication and
eciency. For more information on ASHRAE, please visit www.ashrae.org.
